Toyota 2AZ-FE oil consumption
Hey Scotty I have a 2007 rav4 with 112,000 miles and the dreaded 2AZ-FE 2.4. I have the motor all apart and ordered the ring kit, my question is do I need to replace the pistons is there a defect with them, or do they just get excessively worn? If so how do I check to see if they are worn to the point of replacement. I would just change them but they are $116 a piece. And I’m on a budget. Any help would be appreciated thank you.
Just follow the instructions

Additionally, I’d like to add that you should check for timing chain wear, look at the balancing shaft gears.
